A class instance implementing this interface may customize some aspects of JanusGraph Elasticsearch REST client to implement a custom authentication method.

An implementation must provide a constructor that accepts a String[]. It will receive the value(s) from ElasticSearchIndex.ES_HTTP_AUTHENTICATOR_ARGS. If no authenticator arguments are provided, a zero-size array is passed to the constructor. The constructor must not perform any blocking operations.
